Grid autostop inconsitent results when items after autostop limit are marked

[lachko]

Expected behavior

If autostop is triggered all items after the stopped item must be marked as not attempted and all items recorded have to be incorrect

Actual behavior

in a grid of 50 items and autostop at 5, I can mark items 10, 11, 15 as incorrect and then start marking items 1,2,3,4,5 hence triggering autostop. This created an inconstancy in the results becuase we have reached numberofattemepted items as 5 but we have more items marked as incorrect then those that have been reached thus resulting in negative values:

This is how it looks on the interface: I first marked the third row as incorrect and then the first one to trigger autostop
